Red Hat SummitChapter 5. Ceph Block Device
Block device enhancements are to librbd, and include capping memory utilization for read requests; preventing closure of a closed parent image on failure; ensuring diff tests run properly; and, protecting list_children from invalid pools.
The Ceph kernel block device is only available for RHEL 7 and beyond. It is not available or supported on RHEL 6 and earlier versions of RHEL.
